hi Eric, you could add 

node_name like '%ORC' to the where clause...

Subject: Speeding up my SQL statement


Hi *SM-ers!
I'm using the following SQL statement to retrieve obsolete Oracle backup
files:

select node_name, filespace_name, ll_name, date(backup_date) from backups
where ((days(current_date) - days(backup_date) >= 100)) and hl_name='//'

This returns all Oracle backup files, created more than 100 days ago. These
should not exist anymore.
Since this statement scans ALL (millions!!) backup objects for a hit, it
runs for more than a day!
I'm looking for a way to reduce this, but I don't know how to do this.
If I would be able to limit the scan to only the objects belonging to Oracle
nodes (in our shop, the nodename ends with -ORC) it would finish much
quicker, but I don't know how.
Can anybody tell me if this is possible at all?
Thank you very much for any reply in advance!!!
Kindest regards,
Eric van Loon
